Color Sampler freezes adjustments while using mask

I'm on a Mac, 15.1 ACR but Ventura. I can't replicate it. I do see the change over the mask when dragging the Exposure slider. 

Maybe first off, reset ACR preferences and try again:

Try resetting the Camera Raw preferences:
Hold down the Command key and select Photoshop > Preferences > Camera Raw (macOS) or hold down the Ctrl key and select Edit > Preferences > Camera Raw (Windows).
Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"

If that doesn't work, can you disable GPU in the preferences and let us know if that helps.
